The Standalone Mutual Drainage Reactor is designed to protect communications equipment against the high voltages which may be induced onto telephone pairs, within a telecommunication cable during power fault conditions.
The Mutual Drainage Reactor provides a direct drainage path to ground for common mode induced voltages while maintaining a high impedance to AC differential telephone signals (typically 60 to 4000 Hz). The result is safe, uninterruptible communication before, during, and after fault conditions (ideally used on class “A” circuits).
The Mutual Drainage Reactor is generally intended to be installed outside the zone of influence of high voltage environments, in Central Offices (COs), and field cabinets.
NOTE: Please note that the installation procedure from the installation guide has been updated.
